**Background of TRPM7 Recombinant Protein**
TRPM7 (Transient Receptor Potential Melastatin 7) is a unique bifunctional protein that combines an ion channel with kinase activity, belonging to the TRP channel superfamily. It is ubiquitously expressed in mammalian tissues and plays critical roles in cellular homeostasis, particularly in regulating magnesium (Mg²⁺) and calcium (Ca²⁺) influx. Structurally, TRPM7 consists of a transmembrane ion channel domain fused to a C-terminal serine/threonine kinase domain, enabling it to participate in both ion transport and intracellular signaling.
The channel is constitutively active but modulated by intracellular Mg²⁺ levels, pH, and other physiological factors. TRPM7 is implicated in diverse cellular processes, including cell proliferation, migration, apoptosis, and differentiation. Dysregulation of TRPM7 has been linked to pathologies such as cardiovascular diseases, neurodegenerative disorders, and cancer, highlighting its therapeutic potential.
Recombinant TRPM7 proteins are engineered for in vitro studies to dissect its dual functionality and mechanisms. These proteins are typically expressed in heterologous systems, such as mammalian cells, insect cells, or yeast, to ensure proper post-translational modifications and membrane localization. Purification often involves affinity chromatography and detergent solubilization to maintain structural integrity.
Research using recombinant TRPM7 has advanced understanding of its gating mechanisms, kinase-substrate interactions, and roles in disease. Challenges remain in stabilizing the full-length protein for structural studies, though recent cryo-EM breakthroughs have provided insights into its architecture. Recombinant TRPM7 also aids drug discovery, enabling high-throughput screening for channel or kinase inhibitors.
Overall, TRPM7 recombinant proteins are vital tools for unraveling its multifunctional biology and developing targeted therapies.
